To all whom it may concern for Printing-Presses, of-which the follow inis a specification. v

My invention relates to aux liary tracks for printing presses and isadaptedi to be securedto the frame of a printing pressadjacentthe trackson'the sides of the frame and upon which' the inking trucks run. Onev ofthe objects of my invention'is the pro; vision of an auxiliarytrackwhich can be.

applied to the Gordon type of platenprint ing presses in order that "theinking rolls may be adjusted withrespectto the surface of the forms overwhich the inking rolls pass.

and also on the roller trucks'may be taken up so that proper adjustmentof the inking rolls may be hadat all. times. It is well knownthatlditferent weather conditions at;

feet the composition of the inking rollers,

and that somemethod of adjustment is necessary' in order'to insure thetype surface being properly inked. Heretofore'it has been the custom touse shims of cardboard of various thicknesses in order to properlyadjust the inking rollers with respect to the type. By the use of myinvention all of. this willbe obviated andprop'er adjustment of theinking trucks or rolls can be had at all times. 7 Another obj eot of myinvention is the pro vision of an auxiliary track which fcan easily andsecurely adjusted to different .po -i sitions and which is .also capableofgvery minute adjustment.

Another and further object of my invention is the provision of anauxiliary track which can be securedto a printing press which has beenin operation to such an exrolls'will betaken up; It will be understood,of course, thatthe track upon which thewheelsof the inking rollers runhas been formed heretofore on one edge of the frame members andis'integral with the frame of the printingpress.

Another object of the invention is the pro-; vision of means wherebywear'on'the track 17' respectively in said track, and through a bearingmember 18 which is inserted ineach of the inclined slots 16 and 17. Thebearing member18 has a projection 19 on 7 stood fby reference to theace: drawingsand'in which- 'Oimganymg liigure l is a side elevationv ofim-- proved invention showing one of the tracks applied to a printingpressf I f c I Fig. 2 is a front elevationcof a printin press partsbeing in section...

Aninking'dlskfllfismountedupon the press by means of a standard 12 intheusual manner.

An auxiliary track '13 is secured to :the print lng press [frame by,means of a pair o t-lug, bolts 14:, and 15 respectively, which" passthrough inclined slots or openings lG andc its inner face, thesaidprojection'being ap prox mately thefwidth of one of the ,Slotsspectively, against which theedges of the slots 16 and 17 en age Thebearing member 18may be'ma' e in two parts if so'dsired although Iprefer to make it in one. p1ece. Approximately centrally located of thesaid track-Bis an inclined openingl22 c v c upon thelower edge ofwhichteeth23 are formed. A recess 24: is bored or drilled in the frame 901the printing press and within the head portionl 25 of the key 26 so thati a leverage can be exerted upon the head P01131011 25, which has formedthereon cogs or "teeth 28, 28 which engage the teeth 23 formed'upon thelower edge of the .open-' invention-is further and; better under-rmanner of securing the track tothe print a 16 and; has bearing surfaces20 and 21 re- '100 --which the head portion 25. of a key 26 is inserted.A handle portion 27 is secured to tent that the tracks are'worn, or thetrucks f i of the inking carriage are worn,-so that.

by applying these auxiliary tracksto the of the obtained, whereupon thelug bolts are tightened so" as to hold thetrack securely in position.The bearing member pass is positioned so that the projection 19isinserted within the slots 16 and'17 with the edges ofthe slots incontactwith the bearing surfaces 20 and 21 of thewasher,

the purpose of the projections on the hearing member 18 being to holdthe track securely in alinement so thatas the track is moved both endsof the track willbe moved the same distance, and the track will notturnor bind, or one end move faster than the other. It .willbeunderstood, of course, thatthese tracks are provided in pairs, one

track being secured to each side of the frame of the printing press andare made alike.

except that they are made in rights and lefts as shown in Fig. 2, whereatrack 28" is'shown in section secured to the" printing press frame bymeans of lug bolts 29 and 30. i This track is made like the track here:

tofore described and illustrated in F igQI of the drawings, exceptadapted tobe se cured to theopposite side of the press, so

that further description deemed unnecessary.

It will be understood that in the equip-1 ment of the printing pressesthe roller trucks are wide enough so thatthe rollers carrying thesetrucks will extend over the edge of the Y I claim track 10 and come incontact with the ajuxiliarytracks 13 and 28, so that the tracks can'beapplied to old presses whose tracks have become worn or the rollerscarrying is not effected, The application of the tracks to an old pressis easily accomplished by tapping'holes in the frames for the lug the'frame such as 24 to enable the key, such as 26, to be inserted in therecess and the track moved to proper position when the lugbolts can betightened so as to securely holdthe track.

While I have described more or lessprecisely the details ofconstruction, I do'not wish to be understood as limiting myself thereto,as Icontemplate changes in form and the proportion of parts and thesubstitution of equivalents as circumstances may suggest or renderexpedient without departing from the spirit or scopeof my invention. 7
